I have been having some discussions with someone regarding 220 voltage. My question is, do both legs of a 220 circuit have to have the exact same voltage for it to operate? I've always heard that 110 is not always exactly 110, so if that's the case, will a 220 line run ok, if one leg is say 112 and the other 117 or so?

Thanks,

A few issues:

The Jacuzzi came with two hots and a ground, but no neutral. I have a two pole GFI protecting the Jacuzzi, but I only assume that the GFI will function fully without a neutral on the load side.

I should mention that the GFI is in the main panel. There is a disconnect panel by the Jacuzzi but it has a conventional two pole breaker in there.

Apparently the Jacuzzi has an electrical issue of some sort....

Have a new 30x60 shop with new 200a service - out in the country and away from all the city limits red tape. I did all the exterior and interior connections to the inside breaker box and have wired a 110 and a 50a 220 welder plug just for convenience. The local electric co-op inspected my work before they would connect their service, so I must have passed the first test.

I have not done the permanent interior wiring yet but I'm starting with lights. I have a...

the perimeter of the house.

24 lights of 50 watts, having of total of 1200

watts.

1200 watts divided by 120 volts gives me 10 amps.

I have placed a new breaker of 15 amps. Wich lead

me to think that I will be OK.

The question that I have is: How many lights I am

allowed asper code in one circuit.

IT is 12 lights ONLY????

PLEASE REPLY..thanks]]>

I am familiar with how to convert between watts and amps. And I know how to figure out how many 100 watt bulbs can be on simultaneously before blowing the breaker, but was curious what the pros do. Do I max it out since it is unlikely that all the lights will be on at the same time OR leave 20% of the available 15 amps unused???

Thanks!]]>

I took a voltage reading off of the two legs from Southern California Edison (SCE) going into the main service 100 amp breaker for each of the apartments. All four read 117 volts. Two for each apartment.

Do I need to a dedicated 20amp circuit to these breakers, as if it were a kitchen per NEC rules?

Side question: if I put a sink pump & sump under the sink cabinet, does this need to be on a GFCI too?

Thanks

I had a few questions.

1. Does the "main disconnect" (switch) need to be in it's own junction box?

2. Do I need fittings at the points with red circles? Since the conduit was only for physical protection, I was...
